ROPE FASTENER Filed Jan. 26, 1937 INVENTOR.

TTORNEY.

Patented Apr. 18, 1939 UNITED STATES PATENT OFFICE 2 Claims.

My invention pertains to rope fasteners and more particularly to the type of fastener that may be employed on tow lines, tents, boats, or any other application where rope is used.

5 The objects of my invention is to provide a fastener that will permit a rope to be easily attached or detached without the use of a knot.

Another object of my invention is to provide such a device that will accomplish the purpose for which it is intended without injuring the rope.

A still further object of my invention is to provide a device of the character described that is inexpensive to manufacture yet practical and efficient in every detail.

Other and further objects of my invention Will become more apparent as the description proceeds when taken in conjunction with the accompanying drawing in which Fig. l is a perspective view of the device attached to the end of a rope.

Fig. 2 is a perspective view of the device having the rope attached and showing the manner in which a loop may be formed.

Fig. 3 is a plan view of the device showing the path of the rope when forming a loop.

Fig. 4 is a plan view of the fastener only, and

Fig. 5 is a fragmentary cross sectional view of the device as shown in Fig. 4 when taken at line A-A.

Similar characters of reference indicate corresponding parts throughout the several views and referring now to the same the character I shows a body member consisting of an angular shaped flat portion. There are members II, I2, and I3 extending upward at right angle to the body II) and radially formed to accommodate the rope. The member I2 disposed at a point midway between the members II and I3 projects outward 40 over a projecting ledge I4 forming a part of the body I0, while the members II and I3 project inwardly so that the depending ends extend over the body proper.

At one end of the body I0 and integral with it is a U shaped shank portion I provided with projecting prongs I6. These prongs act as attaching means when formed aroundthe circumference of the rope. At a point centrally disposed between the prongs I6 on the body of the shank portion I5 is a ledge II over which the rope must be placed when engaging the shank portion I5. When the projecting prongs I6 are radially formed over the rope, this ledge II prevents the rope from disengaging the shank portion I5 when a pulling pressure is applied.

In operation the end of a rope is placed into the U shaped shank portion I5 over the ledge Il so that the extreme end of the rope reaches the body section I0 as shown at I8. The projecting prongs I6 are then formed over the rope and being constructed as shown, the opposite points of the prongs engage one another, forming cornplete bands for retaining the rope. As these prongs I6 are forced into position it will cause the rope to engage the ledge I1 permitting the rope to bulge upward so as to prevent slipping from the shank I5.

The rope may then be looped around the object to be held and as it is passed parallel to the members I I and I3 it may be forced over the member I2 causing an irregular path and preventing the rope from slipping due to the frictional contact on the members due to their irregular relation to one another.

It is obvious to anyone familiar with the art that knots in rope are a source of annoyance and trouble and it is very often impossible to open a knot after it has been securely set due to an extreme pull in service. The device illustrated, specified, and claimed eliminates this unnecessary trouble and delay by permitting the user to quickly disengage the rope or take up the slack Without any loss in time or equipment.

In the chosen embodiments of my invention, exemplified by the accompanying drawing, there are present certain novel refinements and improvements not heretofore disclosed in the prior art, and which will be hereinafter more fully referred to and specifically pointed out in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent in the United States, is:

1. A rope fastening device of the character described comprising an elongated fiat body portion, upwardly projecting end members extending from the outer edge of said body portion, an upwardly projecting center member extending inwardly from the outer edge of said body portion and spaced outward from the parallel path of said end members, all of said members having an arced contour, the contour of said center member being opposite from that of said end members, and said body member having a portion offset from the longitudinal plane of the body, clamping members on the oifset portion arranged opposite one another to provide means for fastening the end of a rope when said clamping members encircle said rope.

2. A device of the character described comprising an elongated body, arced Contact members projecting upward at right angles to said body at each end and near the center, said end members having their arced contours opposite from said center member, said center member being positioned outward from the parallel path of said end members and inward from the outer edge of said body, a U-shaped shank member integrally connected to one end of said body, the shank being offset from the longitudinal plane of the body, clamping members arranged in opposite relation to one another on said shank member, and said shank member having a projecting ledge formed in the bight portion of said shank member between said clamping members.
